Referring to FIGS. 1 and 2, a refrigerator 1 according to present embodiment has an approximately rectangular parallelepiped shape. An outer appearance of the refrigerator 1 is defined by a body 10 defining a storage space and a plurality of door provided in the body 10.

The body 10 has an opened front surface. The body 100 is vertically partitioned into a freezer compartment 20 below and a refrigerator compartment 30 and a storage room 100 above. Each of the partitioned spaces may have an independent storage space.

In detail, the freezer compartment 20 is defined at a lower side of the body 10 and may be selectively covered by a drawer-type freezer compartment door 22. A space defined above the freezer compartment 20 is partitioned into left and right sides to respectively define the storage room 100 and the refrigerator compartment 30.

The refrigerator compartment 30 is defined at the right side (when viewed in FIG. 1) above the freezer compartment 20. A plurality of drawers and shelves is provided inside the refrigerator compartment 30 to store foods. The refrigerator compartment 30 may be selectively opened or closed by a refrigerator compartment door 32 pivotably installed on the body 10.

The refrigerator compartment door 32 has a size corresponding to that of the opened front surface of the refrigerator compartment 30. At least portion of the refrigerator compartment door 32 is transparent to enable the refrigerator compartment 30 to be viewed through the refrigerator compartment door 32.

The storage room 100 is defined at the left side (when viewed in FIG. 1) of the refrigerator compartment 30. The storage room 100 is separated from the refrigerator compartment 30 by a barrier 40. Also, the storage room 100 may be selectively covered by a drawer-type door 150.

Hereinafter, the refrigerator compartment door pivotably installed to open and close the refrigerator compartment 30 is referred to as a pivotable door. One or more drawer-type doors for opening and closing the storage room 100 are referred to one or more slidable doors.

When the storage room 100 provided at a side of the refrigerator compartment 30 is used as a refrigerator compartment, the refrigerator compartment door may include the pivotable door as well as the slidable door. Also, when the storage room 100 is used as the refrigerator compartment, the freezer compartment door 22 may include the pivotable door and the slidable door. When the storage room 100 is used as a switching room, the storage room 100 may be denoted as a separate switching room door.

In embodiments disclosed below, when the refrigerator compartment 30 and the storage room 30 are defined in one space, it is obvious to those skilled in the art that the refrigerator compartment door includes the pivotable door and the slidable door.

To avoid confusion in term construction, the refrigerator compartment door used in the detailed description of the present disclosure denotes the pivotable door. However, it is noted that a refrigerator compartment door noted in claims includes the pivotable door as well as the slidable door for opening and closing the storage room used as the refrigerator compartment.

The storage room 100 is partitioned into an upper portion and a lower portion by a partition. That is, the storage room 100 may be divided into a first storage room 100 above and a second storage room 120 below. A first door 130 and a second door 140 are withdrawably provided at the first storage room 110 and the second storage room 120, respectively. If necessary, one storage room 100 may be provided, or two or more storage rooms 100 may be provided.

The first door 130 is withdrawably installed in the storage room 100. The first door 130 may be completely inserted to completely cover the first storage room 110. A receiving part 134 extending backwardly is disposed in a back surface of the first door 130.

The receiving part 134 may have a shape similar to that of a pantry shelf. The receiving part 134 may extend up to a length corresponding to that from the back surface of the first door 130 to an inner rear surface of the first storage room 110. The receiving part 134 may be vertically provided in two stages. Also, the receiving part 134 may be vertically provided in two or multi-stages according to kinds or shapes of received foods.

For example, as shown in FIG. 2, racks may be disposed on both sides of the receiving part 134 to seat an exclusive vessel. Also, the receiving part 134 may have a shape corresponding to that in which wine bottles and vessels are easily received. In addition, the receiving part 134 may have various structures such as a basket or shelf shape.

If necessary, the receiving part 134 may be provided in a single stage when the first storage room 110 is short in vertical length. Also, the receiving part 134 may be provided in two or more stages when the first storage room 100 is long in vertical length.

A second storage room 120 is defined below the first storage room 110. The second storage room 120 may be separated from the refrigerator compartment 30 and the freezer compartment 20, like the first storage room 110. The second storage room 120 is defined above the freezer compartment 20.

A second door 140 withdrawable in front and rear directions is provided on the second storage room 120. The second storage room 120 may be selectively covered by withdrawal of the second door 140.

An ice making compartment 160 may be defined in a back surface of the second door 140. The ice making compartment 160 is a space in which ice is made, and the made ice is stored. An ice maker 162 for making at least ice is disposed inside the ice making compartment 160. The ice maker 162 receives water to make the ice. A water supply process and an ice conveying process may be automatically performed in the ice maker.

When the second storage room 120 is maintained at a temperature corresponding to that of the refrigerator compartment, the interior of the ice making compartment 160 may be thermally insulated from the second storage room 120. That is, the second storage room 120 may be thermally isolated from the ice making compartment 160 by a separate insulation structure. On the other hand, when the second storage room 120 is maintained at a temperature corresponding to that of the freezer compartment, transfer devices as well as the ice maker 162 may be received within the second storage room 120 without requiring a separate insulation or isolation structure.

The ice making compartment 160 may be integrally formed with the back surface of the second door 140, and thus, may be integrally withdrawn together with the second door 140.

At least portion of the ice making compartment may be selectively opened and closed to allow the ice maker 162 within the ice making compartment to be easily repaired and managed.

The ice making compartment 160 may be defined in a relatively lower region of the second door 140. A receiving part 146 for receiving foods may be disposed at a rear side of the second door 140 corresponding to an upper region of the ice making compartment 160. The receiving part 146 may have various structures, like the previously described receiving part 134 of the first door 130. The received foods may be withdrawable together according to the withdrawal of the second door 140. The stored in the receiving part 146 may be divided into refrigerating foods and freezing foods according to an internal temperature of the first storage room 110. A dispenser 142 for dispensing ice and/or water may be disposed in a front surface of the second door 140.

FIG. 3 is a cross-sectional view illustrating a drawer type door of a refrigerator according to an embodiment. Also, FIG. 3 is a cross-sectional view taken along line A-A of FIG. 2.

A configuration of the second door 140 will be described in detail with reference to FIG. 3. The ice making compartment 160 protrudes backwardly from a rear surface of the second door 140. The ice making compartment 160 is disposed in a lower portion of the second door 140, and the receiving part 146 is disposed above the ice making compartment 160.

The ice maker 162 for making ice using the supplied water and the transfer device 170 for transferring the made ice toward the dispenser 142 are disposed inside the ice making compartment 160.

The ice maker 162 is disposed in a rear portion of the ice making compartment. A water supply passage and cool air duct may be separably connected to the ice maker 162 so as to supply water and cool air when the second door 140 is completely inserted.

If necessary, a separate water tank for storing ice making water may be disposed in the ice making compartment. The water tank may be directly filled with the ice making water by a user to supply the water to the ice maker 162.

The transfer device 170 for supplying the ice conveyed from the ice maker 162 to the dispenser 142 may be disposed inside the ice making compartment 160. The transfer device 170 supplies the water to a dispensing hole 144 defined at a position higher than that of the ice maker 162. That is, when the dispensing hole 144 defined in the dispenser 142 is located at a position higher than that of the ice maker 162, the transfer device 170 may be provided as shown in FIG. 1. The transfer device 170 may include a first transfer device 172, a second transfer device 174, and a third transfer device 176.

In detail, the first transfer device 172 may be disposed in a lower portion of the ice maker 162, may be parallel to the ice maker 162, and may be operated by a motor 178. The first transfer device 172 may have a spiral or coil shape to guide the ice conveyed from the ice maker 162 to a front side of the ice making compartment, i.e., toward the second door 140.

The second transfer device 174 may be disposed at a front end portion. The second transfer device 174 may be vertically disposed parallel to the second door 140. Also, the second transfer device 174 may be rotated by the separate motor 178, like the first transfer device 172. On the other hand, a front end of the first transfer device 172 may be connected to a front end of the second transfer device 174 using a medium such as a bevel gear and may be operated by a single motor.

The second transfer device 174 may have a spiral or coil shape to transfer the ice transferred by the first transfer device 172 to an upward direction. At this time, an upper end of the second transfer device 174 may be located at a position higher than that of the dispensing hole 144 of the dispenser 142.

The third transfer device 176 may be disposed at the upper end of the second transfer device 174. The third transfer device 176 is horizontally disposed and has a spiral or coil shape. The third transfer device 176 is rotated by the separate motor 178 to transfer the ice transferred upwardly by the second transfer device 174 to a front direction, i.e., toward the dispensing hole 144. The second transfer device 174 may be connected to the third transfer device 176 using a medium to rotate by a single drive unit. A damper D may be disposed in the dispensing hole 144 to selectively cover the dispensing hole 144. That is, the ice may be selectively dispensed by an operation of the damper D.

If necessary, the transfer device 170 may have a shape different from the spiral or coil shape. A transfer passage 180 having a diameter somewhat greater than that of the transfer device 170 may be defined inside the ice making compartment 160 to smoothly transfer the made ice along the transfer device 170.

The first storage room 110 and the second storage room 120 may be used as a refrigerator compartment or a freezer compartment. The first storage room 110 and the second storage room 120 may be used as the switching room that can be converted into the refrigerator compartment or the freezer compartment by varying a temperature as necessary. At this time, the ice making compartment 160 should be formed as a completely independent insulation space within the second storage room 120.

Although not shown, an evaporator for generating cool air is disposed at a rear side of the freezer compartment 20. The cool air generated by the evaporator is supplied into the freezer compartment 20, the refrigerator compartment 30, the storage room 100, and the ice making compartment 160 to cool the spaces, respectively.

Specifically, when the second door 140 is closed, the cool air duct for supplying the cool air may communicate with the ice making compartment 160 to perform an ice making operation in the ice maker 162 received within the ice making compartment 160.

Hereinafter, an operation of the refrigerator including the above-described components will be described in detail with reference to accompanying drawings.

To receive the foods into the refrigerator 1, the door is opened to store the foods in the refrigerator 1, and then, the door is closed again.

Specifically, in case of the first storage room 110, the user grasps a door handle 132 of the first door 130 to slidingly withdraw the first door 130, thereby to open the first storage room 110. Then, the foods may be received into the receiving part 134 disposed at a rear side of the first door 130. After the foods are received, the first door 130 is inserted to close the first storage room 110.

Similarly, in case of the second storage room 120, the user draws a door handle 144 of the second door 140 to slidingly withdraw the second door 140, thereby to open the second storage room 120. When the second door 140 is withdrawn, the ice making compartment 160 integrally formed with the second door 140 is withdrawn together and is exposed to the outside. Also, the receiving part 146 disposed above the ice making compartment 160 is withdrawn together with the second door 140 and is exposed to the outside.

In case where the dispenser 142 is not provided in the second door 140, when the storage room 100 is opened, at least side of the ice making compartment 160 may be opened to take the ice out of the ice making compartment 160 in a state where the second door 140 is opened.

The water and cool air may be supplied into the second door 140 in a state where the second door 140 is completely inserted into the second storage room 120. Thus, after the second door 140 is completely closed, the ice is made by the ice maker 162, and then, the made ice is dropped downwardly.

The ice stored below the ice maker 162 is horizontally moved by the first transfer device 172, and then, is vertically moved by the second transfer device 174. Then, the ice is horizontally moved by the third transfer device 176 to reach the dispensing hole 144 of the dispenser 142. Finally, the ice transferred into the dispensing hole 144 is dispensed to the outside through a manipulation of the dispenser 142.

For a service of the ice maker 162 or the transfer device 170, the second door 140 is withdrawn to expose the ice making compartment 160 to the outside. In this state, the ice maker 162 or the transfer device 170 may be repaired, for this, the ice maker 162 and the transfer device 170 may be detachably provided.

For receiving the foods into the receiving part 146 of the second door 140, the second door 140 is withdrawn to expose the receiving part 146 to the outside, and then, the foods are received into the receiving part 146. At this time, the foods stored in the receiving part 146 are stored in a refrigerated or frozen state according to an internal temperature of the second storage room 120.

The refrigerator may be also applied to various embodiments except for the previously described embodiment. Hereinafter, a refrigerator according to another embodiment will be described.

FIG. 13 is a front perspective view of a refrigerator according to another embodiment, and FIG. 14 is a partial cross-sectional view of a refrigerator according to the embodiment.

In the present embodiment, a storage rooms is vertically partitioned, and an ice making assembly is disposed in a space different from a dispenser. Thus, the ice making assembly and the dispenser are disposed on doors different from each other, respectively.

Referring to FIGS. 13 and 14, a separate storage room for receiving a drawer-type door is provided at a lateral surface of a refrigerator compartment 30 of a refrigerator 1, and the storage room is separated from the refrigerator compartment 30.

In detail, the storage room is partitioned into a first storage room 710 and a second storage room 720 defined below the first storage room 710 by a partition 190. The first storage room 710 is selectively covered by a first door 730, and the second storage room 720 is selectively covered by a second door 740. An ice making compartment is disposed on a back surface of the first door 730, and an ice making assembly 450 is received into the ice making compartment 460. As described above, the ice making assembly 450 includes a transfer unit including an ice maker 452, an ice bank 454, an auger 458, and a crusher 457 and an electric motor 456 for operating the transfer unit.

In case where the first storage room 710 is used as a freezer compartment, an insulation wall structure defining the ice making compartment 710 may be not necessary. The second storage room 720 may be converted into one of the refrigerator compartment and the freezer compartment.

A supply duct 282 for supplying cool air and a return duct 284, by which the cool air supplied into the ice making compartment 460 or the first storage room 710 returns to an evaporator, extend into a wall defining a body 10. A dispenser 742 for dispensing ice stored in the ice bank 454 or drinking water is disposed in a front surface of the second door 740. A receiving part 744 is disposed on a back surface of the second door 740 corresponding to a rear side of the dispenser 742. According to a design method, the dispenser 736 may have a structure for dispensing only the ice, and a structure for dispensing the drinking water may be not provided. An ice making assembly 450 and/or a water tank 290 for supplying water into a drinking water dispensing hole disposed in the dispenser 742 are disposed inside the second storage room 720. Here, a water supply passage 292 extends from the water tank 290. Since the first door 730 and the second door 740 are slidingly withdrawn, the water supply passage 292 may be detachably coupled to the water tank 290. That is to say, when the first door 730 and/or the second door 740 are/is withdrawn in a front direction, the water supply passage 292 may be separated from the water tank 290. Also, when the first door 730 and/or the second door 740 are/is completely closed, the water supply passage 292 may be variably connected to the water tank 290. At this time, a sealing structure for preventing the water from leaking through a portion connecting the water supply passage 292 to the water tank 290.

An ice suit 748 for discharging the ice stored in the ice bank 454 toward the dispenser 742 is disposed in the back surface of the second door 740. A discharge hole 461 for discharging the ice is defined at a side of a bottom surface of the ice bank 454. In case where the ice making assembly 450 is received into the ice making compartment 450, the discharge hole 461 may be defined in at least one bottom surface of insulation walls defining the ice making compartment 460. A discharge duct 191 connecting the discharge hole 461 to the ice suit 748 is disposed in the partition 190. A damper D may be disposed inside the discharge duct 191. A distance between the ice making assembly 450 including the ice bank 454 and the ice suit 748 may be minimized to improve utilization of inner spaces of the storage rooms 710 and 720. Thus, it is advantageous that the ice making assembly 450 is disposed at a position maximally near to a top surface of the partition 190, and the ice suit 748 is disposed at a position maximally near to a bottom surface of the partition 190. In case where the ice making assembly 450 and the ice suit 748 are spaced a predetermined distance from the partition 190, an inner space of the storage room corresponding to the spaced distance may not receive foods. Thus, it is advantageous that a bottom surface of the ice making assembly 450 or the ice making room 460 is near to the top surface of the partition 190, and an upper end of the ice suit 748 is near to the bottom surface of the partition 190. In this case, the dispenser 742 may be disposed at a position further near to an upper end of the second door 740. Thus, a vertical length of the dispenser 742 may extends vertically so that a position of the bottom is not changed. Therefore, a user having a small height such as a child easily dispenses the ice and water through the dispenser 742.

Since the ice making compartment 460 including the ice making assembly 450 is received into the first storage room 710, and the dispenser 742 is received into the second storage room 720, it may obtain the following effects. That is, the ice making assembly 450 is hardly exposed to the outside of the refrigerator 1 except for a repair due to malfunction. Also, ice making efficiency may be reduced when the ice making assembly 450 is frequently exposed to the outside. Thus, to overcome the above-described limitation, the ice making assembly 450 should be disposed in a separate space within the first storage room 710. The dispenser 742 is disposed in the second door 740. When the second storage room 720 is maintained at a temperature corresponding to that of the refrigerator compartment, it may prevent the water supply passage 292 and the water tank 290 from being frozen over.

Although a separate water storage container such as the water tank 290 is disposed inside the refrigerator 1 in the present embodiment, the present disclosure is not limited thereto. For example, as shown in FIG. 6, the water supply passage may be directly connected to a water supply source.

Also, in the present embodiment, a slight modification may be applied to form the following structure. Although not shown, it is obvious to those skilled in the art that the following structure may be applicable to the present embodiment.

In detail, the second door 740 may be partitioned into a dispenser region and other regions to form two doors. That is, the second door 740 may be divided into two doors to cover the second storage room 720 by the second door 720. For example, the refrigerator 1 may include a first door covering the ice making compartment 460 received into the first storage room 710, a second door covering a portion of the second storage room 720 and including the dispenser and the receiving part, and a third door covering a portion of a lower side of the second storage room 720 and including only the receiving part.

In detail, the storage room is partitioned into a first storage room 710 and a second storage room 720, like the previously described embodiment. The first storage room 710 and the second storage room 720 are selectively covered by a first door 730 and a second door 740, respectively. The first door 730 and the second door 740 are provided in a drawer-type. An ice making assembly 450 is fixed inside the first storage room 710, and a dispenser 736 is disposed on a back surface of the second door 740. Hereinafter, components having the same structure as those of FIGS. 13 and 14 will be given by the same reference numerals.

In detail, an opened front surface of the first storage room 710 may be covered by an insulation wall 711. The first storage room 710 may be maintained at a temperature corresponding to that of a freezer compartment 20. An ice making assembly 450 is fixed inside the first storage room 710. As described above, the ice making assembly 450 may include an ice maker 452, an ice bank 454, an electric motor 456, a crusher 457, and an auger 458. The ice making assembly 450 may further include a cooling fan 459 according to a design condition. The cooling fan 459 uniformly distributes cool air supplied from a supply duct 282 to the inside of the first storage room 710 and quickly supplies the cool air into the ice maker 452. A structure of the cooling fan 459 may be applicable in the same manner to the previously described embodiments.

A water tank 290 is disposed inside the second storage room 720. A water supply passage 292 is detachably connected to the water tank 290. Although the water supply passage 292 for supplying water into the ice maker 452 is directly connected to a water supply source along a well defining a refrigerator body 10 in the present embodiment, the present disclosure is not limited thereto. For example, the same structure as those of the embodiments shown in FIGS. 13 and 14 may be applicable in the present embodiment.

In the present embodiment, a portion of the first door 730 covers a portion of an upper side of the second storage room 740. Thus, a frame 722 for preventing cool air from leaking is disposed at a front side of the second storage room 720 corresponding to a region in which a lower end of the first door 730 is in contact with an upper end of the second door 740. That is, a gasket disposed on a back surface of the lower end of the first door 730 and a gasket disposed on a back surface of the upper end of the second door 740 are closely attached to a front surface of the frame 722 to prevent the cool air from leaking.

In another embodiment, when the first door 730 has a size in which only the first storage room 710 is covered, a separate frame may be not necessary, and the partition 190 may serve as the frame.

Also, in the present embodiment, a dispensing structure for dispensing drinking water may be not provided in the dispenser 736, and only an ice dispensing structure may be provided in the dispenser 736. In this case, the water supply tank 290 and the water supply passage 292 for supplying the drinking water may be not necessary.

According to the above-described structure, like the previously described embodiment, when the first door 730 is withdrawn, the ice making assembly 450 is maintained in a state in which the ice making assembly 450 is fixed inside the first storage room 710. That is, since the ice making assembly 450 need not be frequently exposed to the outside by a user, the ice making assembly 450 is not exposed to the outside even if the doors 730 and 740 are withdrawn.

In the present embodiment, since the ice making assembly 450 is fixed inside the first storage room 710, a separate insulation wall structure surrounding the entire ice making assembly 450 need not be provided. That is, it may be enough to provide only the insulation wall 711. However, a separate insulation wall defining the ice making compartment may be provided according to a design condition. The insulation wall 711 may be pivotably provided about an upper end thereof to allow the ice making assembly 450 to be separated.

The two doors for respectively opening and closing the first storage room 710 and the second storage room 720 may be integrally formed in one body. That is, the first door 730 and the second door 740 are not divided, i.e., a single door may be provided to selectively open and close the first storage room 710 and the second storage room 720. This structure is referred to as a plurality of storage rooms/single door structure. In this case, when the second storage room 720 is opened, the first storage room 710 may be opened together. However, the insulation wall 711 may prevent an external air from being introduced into the first storage room 710. Also, in case of the single door structure, the frame 722 need not be provided.

On the other hand, the first door 730 may be divided into two doors.

In detail, the first door 730 may be divided into an upper door for covering only the ice making compartment 710 and a lower door including the dispenser. The upper door may open and close the ice making compartment instead of the insulation wall 711. A dispenser 736 may be disposed in the lower door, and a receiving part may be disposed at a rear side of the dispenser 736. Thus, the second storage room 720 may be opened and closed by the lower door including the dispenser 736 and the second door 740. This structure is referred to as a plurality of storage rooms/a plurality of doors structure. That is, one door may open and close a portion or the whole of one storage room.

FIG. 17 is a front perspective view of a refrigerator according to another embodiment, and FIG. 18 is a partial cross-sectional view of a refrigerator according to the embodiment.

In the present embodiment, an ice making assembly is fixed inside a storage room, and only a dispenser is disposed on a back surface of a door for opening and closing the storage room. Thus, the storage room forms one space.

Referring to FIGS. 17 and 18, a refrigerator 1 according to the present embodiment includes a refrigerator compartment 30, a freezer compartment 20, and a storage room 760 defined at a side of the refrigerator compartment 30.

In detail, the storage 760 is provided in one space, and an ice making compartment 460 is defined above the storage room 760. As described above, the ice making compartment may be separated from the storage room 760 by a separate insulation wall structure. According to the separate insulation wall structure, an internal temperature of the ice making compartment 460 may be different from that of the storage room 760. An ice making assembly 450 is received into the storage room 760. The storage room 760 includes an ice maker 452, an ice bank 454, an electric motor 456, a crusher 457, and an auger 458, and/or a cooling fan 459. A front surface of one of insulation walls defining the ice making compartment 460 may be pivotably disposed about an edge portion of a side thereof to allow the ice making assembly 450 to be separated. A discharge hole 461 for discharging ice is defined in a bottom surface of one of the insulation walls defining the ice making compartment 460.

An opened front surface of the storage room 760 is selectively covered by a door 750. The door 750 may have a configuration and size in which the first door and the second door of the previously described embodiment are integrally formed in one body. A dispenser 736 is disposed at a side of the door 750. That is, a recess portion for receiving a container is disposed on a front surface of the door 750, and an ice suit 748 for guiding a discharge of ice is disposed in a back surface of the door 750. When the door 750 is completely closed, an upper end of the ice suit 748 communicates with the discharge hole 461. Thus, the ice discharged from the ice bank 456 passes through the discharge hole 461, is guided by the ice suit 748, and is discharged from the dispenser 736.

Although not shown, the ice making compartment 460 may be disposed on the back surface of the door 750 to provide a structure in which the ice making compartment 460 is withdrawn together with the door 750. This will be construed as being included in the present disclosure.

Also, the door 750 may be partitioned into two doors, and the storage room 760 may be also partitioned into two storage rooms. It may be easily modified from FIGS. 17 and 18 by those skilled in the art. That is to say, the door 750 may be partitioned into a first door including the dispenser 736 and/or the receiving part and a second door including only the receiving part. Also, the storage room 760 corresponding to the door 750 may be partitioned into a first storage room receiving the ice making assembly 460 and a rear end portion of the dispenser 736 and a second storage room receiving the receiving part disposed on the second door. Thus, the partitioned first storage room may be opened and closed by the first door, and the partitioned second storage room may be opened and closed by the second door. Of course, the ice making assembly 460 is fixed inside the partitioned first storage room. This structure is referred to as a plurality of storage rooms/a plurality of doors structure. Thus, one door may open and close one storage room.

FIG. 19 is a front perspective view of a refrigerator according to another embodiment, and FIG. 20 is a partial cross-sectional view of a refrigerator according to the embodiment.

In the present embodiment, a storage room separated from a refrigerator compartment and a freezer compartment and a door for opening and closing the storage room are provided in one space and a single door to provide only a dispenser for dispensing drinking water within the door.

Referring to FIGS. 19 and 20, a body 10 of a refrigerator 1 according to the present embodiment includes a refrigerator compartment 30, a freezer compartment 20, and a storage room 760. The storage room 760 is covered by a drawer-type door 750 that is slidingly withdrawn.

In detail, at least one or more receiving parts are disposed on a back surface of the door 750. A variety of containers is seated on the receiving parts 754. A dispenser 756 having a recessed shape and dispensing drinking water is disposed in a front surface of the door 750. A water supply passage 292 extends up to a top surface of the dispenser 756.

In further detail, a water tank 290 is disposed inside the storage room 760. The water supply passage 292 extends from the water tank 290 up to the dispenser 256. As shown in FIG. 20, the separate water tank 290 for supplying the drinking water may be provided. Alternatively, the water supply passage 292 may be directly connected to a water supply source.

The water supply passage 292 has one end detachably connected to the water tank 290. Thus, when the door 750 is opened, the water supply passage 292 is separated from the water tank 290, and when the door 750 is completely closed, the water supply passage 292 is coupled to the water tank 290.

Although the dispenser 756 is disposed at an upper portion of the door 750 in the present embodiment, the present disclosure is not limited thereto. For example, like a dotted portion shown in FIG. 19, the dispenser 756 may be disposed at a position near to the door 750. Therefore, a user having a small height such as a child may easily dispense ice and water.

Also, although a dispenser for dispensing ice is not provided, and only a dispenser for dispensing drinking water is provided in the present embodiment, as well as, the door 750 for opening and closing the storage room 737 is provided in only one as an example, the present disclosure is not limited thereto. For example, the door 750 for opening and closing the storage room may be provided in plurality, like the previously described embodiment.

For example, doors for opening and closing the storage room may be disposed at upper and lower sides, respectively, and a dispenser for dispensing the drinking water may be disposed on any one door. Also, the storage room 760 may be partitioned into a plurality, and the partitioned storage rooms may be maintained at temperatures different from each other.

FIG. 21 is a vertical cross-sectional view of a refrigerator according to another embodiment, FIG. 22 is a bottom perspective view illustrating a first door of a refrigerator according to the embodiment, and FIG. 23 is a rear perspective view illustrating a second door of a refrigerator according to the embodiment.

Referring to FIGS. 21 to 23, in the present embodiment, a first door 730 covers the whole of a first storage room 710 and a portion of a second storage room 720. A second door 740 covers a remaining portion of the second storage room 720. Moreover, an ice making assembly 450 is disposed on a back surface of the first door 730 corresponding to a region in which the portion of the second storage room 720 is covered. A dispenser 746 for dispensing ice and/or water is disposed in a front surface of the second door 740.

In the present embodiment, a water supply passage 292 for supplying the water into an ice maker 452 and the dispenser 746 is directly connected to a water supply source. When the first door 730 and/or the second door 740 are/is withdrawn, the water supply passage 292 is separated at any position, and the water supply is stopped by an opening/closing valve V disposed at the separated position.

A partition or a frame may be not provided between a lower end of the first door 730 and an upper end of the second door 740, and a pillar 50 may be pivotably disposed on a back surface of the lower end of the first door 730. A structure and operation of the pillar 50 will be described below in detail with reference to accompanying drawings.

A discharge duct 462 for guiding a withdrawal of ice is disposed at a front side of a bottom surface of the ice making assembly 450 and extends toward the dispenser 740. In detail, an ice suit 748 for guiding the withdrawal of the ice is disposed at an upper side of the dispenser 740. An end portion of the discharge duct 462 extends near to an inlet port of the ice suit 748.

The discharge duct 462 does not extend below an upper end of the second door 740. That is, an end portion of the discharge duct 462 may maximally extend up to a plane L1 horizontally parallel to the upper end of the second door 740. This is done because it prevents the discharge duct 462 form interfering with the second door 740 when the first door 730 is opened in a state where the second door 740 is closed.

The inlet port of the ice suit 748 protrudes toward the discharge duct 462. However, the inlet port does not extend above a plane L2 horizontally parallel to a lower end of pillar 50. That is, this is done because it prevents the inlet port of the ice suit 748 from interfering with the pillar 50 when the second door 740 is opened in a state where the first door 730 is closed.

Dampers D may be disposed inside the discharge duct 462 and the ice suit 748, respectively, to prevent the ice from being dispensed when any one of the first door 730 and the second door 740 is opened.

As a result, the end portion of the discharge duct 462 is not closely attached to the inlet port of the ice suit 748. Thus, the dampers D may be manipulated to prevent cool air supplied into an ice maker 460 from leaking into the second storage room 720 or the dispenser 746. For this, a passage formed by the discharge duct 462 and the ice suit 748 is covered by the dampers D, except when the ice is dispensed.

The end portion of the discharge duct 462 has an inside diameter d1 equal to or less than that of the inlet port of the ice suit 748 to prevent a portion of the ice from being introduced into the second storage room 720.

Referring to FIG. 21, a rail member 60 may be disposed on both lateral surfaces of the receiving part 734. The rail member may 60 be withdrawn in multi-step. That is, the rail member 60 include fixed rails 61 respectively fixed to the both lateral surfaces of the receiving part 734 and a movement rail 62 movably connected to the fixed rails 61. A support structure for slidingly supporting the rail member 60 may be disposed on an inner sidewall of the second storage room 720. The rail member 60 has the same structure as or is similar to a rail member that will be described in detail in the following embodiment.

FIG. 24 is a side cross-sectional view of a refrigerator according to another embodiment.

Referring to FIG. 24, a refrigerator according to the present embodiment has the same structure as that shown in FIG. 21, except that an ice making compartment 460 is fixed inside a storage room.

As shown in FIG. 24, the ice making compartment 460 is fixed to a rear surface of a second storage room 720, and an ice making assembly 450 is received into the ice making compartment 460. Thus, a portion of an upper side of the first door 730 covers the whole of the first storage room 710, and a portion of a lower side of the first door 730 covers a portion of the second storage room 720. A dispenser 746 is disposed on a back surface of the second door 740, and the second door 740 covers the remaining portion of the second storage room 720.

A discharge duct 462 extends from a bottom surface of the ice making compartment 460, and an end portion of the discharge duct 462 extends toward an ice suit 748 disposed above the dispenser 746. That is to say, the discharge duct 462 may inclinedly extend in a front direction up to an inlet port of the ice suit 748. This is done because the ice making compartment 460 is not moved even if the first door 730 is withdrawn forwardly, and because it does not matter that the end portion of the discharge duct 462 extends up to a position lower than that of an upper end of the second door 740. This is different from the embodiment of FIG. 21. Thus, since a distance between a lower end of the discharge duct 462 and an inlet of the ice suit 748 may be minimized, leakage of cool air may be minimized. Of course, in case of the present embodiment, dampers D may be disposed inside the discharge duct 462 and the ice suit 748, respectively.

FIGS. 25 and 26 are partial perspective views of a power supply structure connected to a water supply passage and a dispenser provided in a refrigerator according to an embodiment, and FIG. 27 is a cross-sectional view taken along line B-B of FIG. 26.

A water supply passage and a wire shown in FIGS. 25 to 27 may be commonly applicable to all of the previously described embodiments and the following embodiments. It is to be understood that the water supply passage is merely illustrative of one of various embodiments. A structure of a refrigerator, based on the structure of the refrigerator shown in FIG. 21, will be described below.

Referring to FIG. 25, a water supply passage 292 extending from a water tank or a water supply source extends along a sidewall of a refrigerator body 10. The water supply passage 292 extends up to a front surface of the sidewall of the refrigerator body 10, and an opening/closing valve V is disposed at an end portion of the water supply passage 292.

Referring to FIG. 26, a water supply passage 292 for dispensing drinking water within a second door 740 extends toward a dispenser. An end portion of the water supply passage 292 protrudes from an edge portion of a back surface of the second door 740. The end portion of the water supply passage 292 is selectively coupled to the opening/closing valve V. That is, when the second door is completely closed, the water supply passage of the refrigerator body 10 and the water supply passage of the second door 740 are connected to each other, and the opening/closing valve V is opened.

Although only the water supply passage for dispensing the drinking water extends along the refrigerator body in the present embodiment, the present disclosure is not limited thereto. For example, when an ice making compartment is fixed to the first door or the second door, a water supply passage for making ice may be realized also using the same manner.

As described above, rail members 60 are disposed on both lateral surfaces of a portion corresponding to a bottom surface of a receiving part 734. A wire P extends inside one rail member 60 and is connected to a controller (not shown) for operating a display or dispenser disposed in the second door 740.

Referring to FIG. 27, the wire P extends inside a fixed rail 61 fixed to a lateral surface of the receiving part 734. The wire P may be wound in a spiral shape and have a predetermined elasticity. Thus, the wire P may extend according to forward and backward movements of the second door 740, and then, returns to prevent the wire from being damaged.

FIGS. 28 and 29 are partial perspective views of a power supply structure connected to a dispenser of a refrigerator according to another embodiment.

Referring to FIGS. 28 and 29, a refrigerator according to the present embodiment has the same structure as that shown in FIGS. 25 and 26, except for a power supply structure. Thus, duplicated descriptions of other components except for the power supply structure will be omitted.

In detail, in the present embodiment, a wire P extends along an inner sidewall of a refrigerator body 10. A socket 600 may be disposed on a front surface of the sidewall of the refrigerator body 10, i.e., a surface in contact with a back surface of a first door 730 or a second door 740. The wire P is connected to the socket 600.

A plug 601 may protrude from a surface corresponding to the socket 600 of the back surface of the second door 740 (or the first door 730). A battery 602 for an electric charging may be laid inside the second door 740 and be connected to the plug 601. The battery 602 is electrically connected to a controller for controlling operations of a display attached to a front surface of the second door 740 and other electric components. It is obvious that the plug 601 may be disposed on the refrigerator body 10, and the socket 600 may be disposed on the second door 740.

When the second door 740 is completely closed, the plug 601 is inserted into the socket 600. Thus, current flows to charge the battery 602. When the second door 740 is withdrawn forwardly, the plug 601 is separated from the socket 600 to stop the charging.

When the second door 740 is completely closed, a variety of electric components including the display disposed on the second door 740 is operated by the current supplied through the wire p. On the other hand, when the second door 740 is opened, the display and other electric components are operated by the current supplied from the battery 602.

FIGS. 30 and 31 are partial perspective views of a refrigerator according to another embodiment.

Referring to FIGS. 30 and 31, in the present embodiment, an ice making compartment is defined on a back surface of a storage compartment door, and an ice making assembly and a dispenser are received into the ice making compartment. A structure in which a water supply passage for making ice and a water supply passage for dispensing drinking water extend toward a door will be described in detail.

For easy understanding of description, a structure according to the present embodiment, realized on a back surface of a second door 740 for opening and closing a second storage room, will be described below.

In detail, an ice making compartment 770 is vertically disposed on a back surface of the second door 740. An ice making compartment door 771 is pivotably disposed on a side of the ice making compartment 770.

An ice maker 452 and an ice bank 454 constituting an ice making assembly 450 are received into the ice making compartment 770. An auger 458 and a crusher 457 are provided inside the ice bank 454. An electric motor (not shown) for operating the auger 458 and the crusher 457 may be laid inside the second door 740. In detail, the ice maker 452 may be disposed on an inner top surface of the ice making compartment 770, and the ice bank 454 may be detachably disposed direct below the ice maker 452. A dispenser 746 including an ice suit 748 is disposed at a lower side of the ice bank 454. That is, the ice bank 454 may be detachably disposed on a top surface of the dispenser 748. The ice bank 454 may be slidingly movable laterally from the top surface of the dispenser 748. Thus, a user may open the ice making compartment door 771 to easily separate the ice bank 454 from a refrigerator in a state where the second door 740 is withdrawn.

Although a transfer unit including the auger 458 and the crusher 457 extends forwardly and backwardly in the present embodiment, the present disclosure is not limited thereto. For example, a vertical auger structure disclosed in U.S. Issued U.S. Pat. No. 6,082,103 may be applicable to the present embodiment. Also, an auger structure, in which a rotation axis is inclined, disclosed in Korean Published Applications No. 2008-0053503 may be applicable to the present embodiment. Here, the rotation axis may extend in a direction crossing the second door 740 and may be inclined in up and down or left and right directions. Or, the rotation axis may extend in a direction parallel to the second door 740 and may be inclined in a vertical direction.

A pair of water supply passages 292 within sidewalls of a second storage room 720 opened and closed by the second door 740 may extend in a front direction, and opening/closing valves V may be disposed at front ends of the water supply passages 292. End portions of the water supply passages selectively coupled to the opening/closing valves V may protrude from an edge portion of a back surface of the second door 740. Since structures of the water supply passages ware previously described, duplicated descriptions thereof will be omitted.

A receiving part 744 may be disposed at a rear side of the ice making compartment 770, and rail members may be disposed on both lateral surfaces of the receiving part 744 to allow the second door 740 to be withdrawn forwardly.

FIG. 32 is a perspective view illustrating a structure of an ice-making assembly of a refrigerator according to an embodiment.

Referring to FIG. 32, an overflow prevention unit is illustrated in the present embodiment. The overflow prevention unit prevents water supplied into an ice making assembly from overflowing due to an inertial force generated when a storage room door is moved forwardly and backwardly.

In detail, an ice maker 452 is disposed horizontally or vertically inside an ice making compartment 460. A water supply passage 292 extends in a direction crossing the ice making compartment 460 toward the ice maker 452.

A discharge hole 461 is defined in a bottom surface of the ice making compartment 460. Also, a guide member is disposed to transfer ice separated from the ice maker 452 toward the discharge hole 461. The guide member may include a guide plate 459 extending from a lateral surface of the ice maker 452. In detail, the guide plate 459 inclinedly extends downwardly from a lateral end of a top surface of the ice maker 452 to approach to the discharge hole 461.

An overflow prevention part 453 may extend from an edge portion of the top surface of the ice maker 452. In detail, in case where the ice making compartment 460 is disposed on a storage room door, water stored in the ice maker 452 may overflow due to inertia when the storage room door is moved forwardly and backwardly. The overflow prevention part 453 may be provided to prevent the water from overflowing. The overflow prevention part 453 may have a structure in which water overflowing by the inertia returns again to the ice maker 452. That is, the overflow prevention part 453 may extend in a direction crossing an inertia direction, and an upper portion thereof may be rounded. Thus, the water soars upwardly from the ice maker 452 flows along an inner surface of the overflow prevention part 453 to return again to the ice maker 452. The overflow prevention part 453 may have various shapes according to an internal structure of the ice making compartment 460 and an installation direction of the ice maker 452. Alternatively, a residual water tray for receiving the overflowing water may be disposed on a bottom surface of the ice maker 452.

In the present disclosure, the ice making assembly may be defined as an ice making mechanism, as well as, a structure including the ice making assembly and the ice making compartment may be inclusively defined also as the ice making mechanism. That is, a structure including at least ice making assembly may be defined as the ice making mechanism. It may be widely construed that the ice making compartment denotes a physical configuration such as an insulation wall structure surrounding the ice making assembly as well as an inner space defined by the insulation wall structure.

Also, the storage room disclosed in the present disclosure, i.e., the first storage room and the second storage room may be used as one of the refrigerator compartment and the freezer compartment. In addition, the storage room may be used as the switching room in which the refrigerator compartment and the freezer compartment may be mutually converted according to a user s selection or a driving condition.

In a structure of the refrigerator according to the previously described embodiments, the slidable door that is movable in forward and backward directions, but the pivotable door, is provided at a side of the refrigerator door. Thus, when the refrigerator is installed at an edge portion of an indoor space, a door closely attached to a wall is not rotated at an angle greater than about 90 degrees. However, the prevent disclosure may overcome such a limitation.

Also, the storage room disclosed in the present disclosure has a width relatively narrower than the refrigerator compartment. However, since long containers such as a bottle may be easily received into the storage room, space utilization of the inside of the refrigerator may be improved.

FIG. 33 is a perspective view illustrating an outer appearance of a refrigerator according to an embodiment, and FIG. 34 is a perspective view of a refrigerator when a refrigerator door is opened, according to an embodiment.

Referring to FIGS. 33 and 34, a refrigerator of the present embodiment is almost similar to those of FIGS. 1 and 2. However, a separate barrier for partitioning the inside of the refrigerator is not provided, and a refrigerator door for opening and closing a refrigerator compartment defined in one space includes a pivotable door and a plurality of slidable doors.

In detail, a refrigerator according to the present embodiment includes a body 10 in which a refrigerator compartment 30 and a freezer compartment are defined, a refrigerator compartment door 32, a freezer compartment door 22, a first door 130, and a second door 140. The refrigerator compartment 30 and the freezer compartment are selectively covered by the refrigerator compartment door 32, the freezer compartment door 22, the first door 130, and the second door 140, respectively. Also, an outer appearance of the refrigerator is defined by the doors.

The refrigerator compartment 30 and the freezer compartment 20 are defined at upper and lower portions of the body 10, respectively. The refrigerator compartment 30 is covered by the refrigerator compartment door 32, the first door 130, and the second door 140. The freezer compartment 20 is covered by the freezer compartment door 22.

In detail, the refrigerator compartment door 32 covers a portion of an opened front surface of the refrigerator compartment 30 and is pivotably disposed on a body 10. For this, the refrigerator compartment door 32 is coupled to the body 10 by a hinge 34.

A vertical length of the refrigerator compartment door 32 corresponds to a vertical length of the refrigerator compartment 30. Also, the refrigerator compartment door 32 has a width less than that of the refrigerator compartment 30. Thus, the refrigerator door 32 may covers a remaining portion, exclusive of a predetermined horizontal width of the refrigerator compartment 30, by a rotation thereof.

Al least portion of the refrigerator compartment door 32 may be formed of a transparent or translucent glass material to enable the refrigerator compartment 30 to be viewed through the refrigerator compartment door 32. Specifically, even foods received in a first door 130 and a second door 140 that will be described below may be viewed through the refrigerator compartment door 32 from the outside.

A front surface of the refrigerator door 32 may be formed of a glass material, and a circumference thereof may be formed of a plastic or metallic material.

The rail member 60 for withdrawing the second door 440 is disposed on inner lower and left side surfaces of the refrigerator compartment 30 to support and slidingly move the first door 430.

Receiving parts 434 and 442 for receiving foods are disposed on the first door 430 and the second door 440. A dispenser 436 for dispensing water and ice is disposed in a front surface of the first door 430. Considering a height of a user, the dispenser 436 may be disposed at a lower side of the first door 430.

An ice making compartment 460 is disposed at an upper side of the first door 430. An ice maker 452 and an ice bank 454 are received into the ice making compartment 460. The ice making compartment 460 may be formed with an independent insulation space within the refrigerator compartment 30.

The ice making compartment 460 may be detachably coupled to a back surface of the first door 430 and may be integrally formed by a door liner defining the back surface of the first door 430.

The ice making compartment 460 may extend from the back surface of the first door 430 toward a rear direction, and thus may be adjacent to a rear surface of the refrigerator compartment 30. Also, when the first door 430 is completely inserted, a cool air duct 480 disposed inside the body 10 communicates with the inside of the ice making compartment 460.

In detail, the cool air duct 480 includes a supply duct for guiding cool air into the ice making compartment 460 and a return duct for guiding the cool air toward an evaporator. A cool air inlet 462 and a cool air outlet 464 are defined in a rear wall of the ice making compartment corresponding to the supply duct 482 and the return duct 484, respectively.

Thus, when the first door 430 is completely inserted, the supply duct 484 may communicate with the cool air inlet 462, and the return duct 484 may communicate with the cool air outlet 464 to continuously circulate the cool air between the ice making compartment 460 and the evaporator.

An auger 458 operated by an electric motor 456 and a crusher 457 disposed on the same rotation axis to crush the ice are disposed in the ice bank 454 within the ice making compartment 460. A power source for operating the electric motor 456 of the ice bank 454 and the ice maker 452 may be inputted by a power connector connected to the electric motor 456 and the ice maker 452 when the first door 430 is completely inserted.

A water tank 490 for supplying the water into the ice maker 452 and the dispenser 436 is disposed at a side of the ice making compartment 460. The water tank 490 may be detachably disposed, and thus filled with a desired amount of the water by a user. Thus, when the first door 430 is withdrawn, the ice making compartment 460 and the water tank 490 may be withdrawn together with the first door 430 in front and rear directions.

The water stored in the water tank 490 may be supplied into the dispenser 436 and the ice maker 452 through a water supply passage 492. The water supply passage 492 connects the water tank 490 to the dispenser 436 and the ice maker 452. At least portion of the water supply passage 492 may be buried inside insulation foam filled inside the first door 430.

The water tank 490 may be disposed in the body 10 spaced from the ice making compartment 460. The water tank 490 may be connected to a water supply passage directly connected to the ice maker 452 and the dispenser 436. At this time, the water supply passage may be selectively connected to a connection part 468 disposed at a side of the ice making compartment 460. A valve may be disposed in the water supply passage.

Gaskets 438 for preventing the cool within the refrigerator compartment 30 air from leaking are disposed on back surfaces of the first door 430 and the second door 440. A pillar 50 is disposed at a position adjacent between the first door 430 and the second door 440.

The pillar 50 covers a space between the first door 430 and the second door 440. The pillar 50 is disposed at a lower end of the back surface of the first door 430. The pillar 50 is selectively pivoted according to the withdrawal of the first door 430 to selectively cover the space between the first door 430 and the second door 440.

In detail, the pillar 50 has a length corresponding to a horizontal width of the first door 430. When the first door 430 is inserted, the pillar is pivoted. As a result, a lower end of the first door 430 and an upper end of the second door 440 are in contact with a front surface of the pillar 50 to prevent the cool air within the refrigerator compartment 30 from leaking between the first door 430 and the second door 440.

The pillar 50 is hinge-coupled to the lower end of the first door 430. The pillar 50 is closely attached to the first door 430 by an elastic member 52 in a state where the front surface of the pillar 50 is inclined downwardly when an external force is not applied to the elastic member 52. The pillar 50 may be covered by a front surface of the first door 430. Thus, the pillar 50 may be not exposed to the outside when viewed from a front direction of the first door 430.

The elastic member 52 disposed in the pillar 50 may have a coil spring shape. The elastic member 52 may connect the pillar 50 to a side of the first door 430. The pillar 50 may be closely attached the lower end of the first door 430 due to elasticity of the elastic member 52 if the external force is not applied to the pillar 50.

The elastic member 52 may have various shapes except for the coil spring shape. Also, the elastic member 52 may be disposed at various positions to provide an elastic force to the pillar 50.

A guide protrusion 54 protruding outwardly is disposed at one end of the pillar 50. The guide protrusion 54 may moved along a guide groove 70 defined in a lateral surface corresponding to the inside of the refrigerator compartment 30. Surfaces of the guide groove 70 and the guide protrusion 54, which correspond to each other, may be rounded with a predetermined curvature to smoothly rotate the pillar 50.

In detail, the guide groove 70 is opened in a front direction and is depressed inwardly. The guide groove 70 is curved inwardly with a predetermined curvature. A curved part 56 corresponding to the curvature of the guide groove 70 is disposed on the guide protrusion 54 contacting with the guide groove 70. Thus, when the guide protrusion 54 of the axially coupled pillar 50 is moved along the guide groove 70 fixed to an inner wall of the refrigerator compartment 30, the pillar may be rotatable.

FIG. 40 is a view illustrating successive operations of a pillar according to another embodiment.

Referring to FIGS. 37 and 40, when the first door 430 is opened, the front surface of the pillar 50 is inclined downwardly due to an elastic restitution force applied by the elastic member 52.

When the first door 430 is inserted in a rear direction, the curved part 56 of the guide protrusion 54 contacts with the guide groove 70. When the first door 430 is further inserted, the pillar 50 is moved backwardly along the first door 430 to rotate about a rotation axis in a count-clockwise direction. At this time, the curved part 56 disposed on the guide protrusion 54 is slidingly moved along an inner surface of the guide groove 70.

When the first door 430 is completely inserted, the curved part 56 of the guide protrusion 54 is completely rotated along the guide groove 70. At this time, the front surface of the pillar 50 is faced in a front direction and is in contact with the lower end of the first door 430 and the upper end of the second door 440.

The curved part 56 of the pillar 50 is coupled to the inside to the guide groove 70. The front surface of the pillar 50 is rotated by 90 degrees in a count-clockwise direction when compared to a state in which the first door 430 is opened and is faced in a front direction of the refrigerator 1.

In this state, the elastic member 52 completely extends. When the first door 430 is withdrawn again, the pillar 50 is rotated in a clockwise direction due to the elastic restitution force of the elastic member 52. At this time, the curved part 56 of the pillar 50 is slidingly moved along the guide groove 70.

FIG. 41 is a perspective view of a refrigerator when a door is opened, according to another embodiment.
